Learn more about the features and technical specifications of the Geotab GO9 device, including GPS technology, Geotab IOX expandability, engine and battery health assessments, and the ability to communicate on the LTE network.
Geotab’s GO9 telematics device is the most powerful yet. The GO9 offers a 32-bit processor, 4x more memory and 5x more RAM than the GO8®. Similar to the GO8, the GO9 offers state-of-the-art GPS technology, g-force monitoring, GEOTAB IOX® expandability, engine and battery health assessments, and communication on the LTE network*.
Using Geotab’s patented tracking algorithm, the GO9 accurately recreates vehicle trips and analyzes incidents. The GO9 also offers in-vehicle alerts to instantly notify drivers of infractions and — with hardware Add-Ons — provides live coaching for driver’s on-road performance. The GO9 does not require a dash-mounted antenna or any wire splicing.
Geotab platform security is designed for end-to-end protection of your data.

Before installing the GO™ device, please record the device serial number. The serial number is used to verify the communication status of the GO device.
Carefully read the device release notes (goo.gl/fZURff) or the vehicle specific installation notes (goo.gl/MCIXt0) to verify that we support your vehicle. If you have any questions or concerns, please consult your Authorized Reseller.
Ensure no dash warning lights are on in the vehicle while it is running, and all other functions, such as headlamps and flashers etc. work prior to installing the device.
Before Installation, add the device to your MyGeotab database using the device serial number. This will ensure all data logged from point of install onward is sent to your database.
✱ NOTE: You must select the correct Geotab hardware suitable for your specific installation environment and vehicle use. For installations where exposure to the elements (e.g., liquids, dust, or interior wet cleaning/powerwash) is anticipated, select the GO RUGGED® device (GR8 rated IP67, and GR9 rated IP68 and IP69K). For additional information regarding environmental contaminants, see the applicable installation instructions as well as the Important Safety Information & Limitations of Use section below.
Read important related safety information and limitations of use following these installation instructions. Read and follow all instructions and warnings to prevent serious injury and/or vehicle damage.
WARNING! Prior to GO installation, read and follow important safety information including limitations of use located following these installation instructions. Always read and follow all safety information to prevent loss of vehicle control and serious injury.
WARNING! Some installations are not straightforward and must be completed by an Authorized Geotab Installer to ensure a secure installation. An unsecure device installation can cause poor electric and/or data connection that can lead to short circuits and fires or cause malfunctions of vehicle controls that can result in serious personal injury or significant damage to your vehicle. Some examples requiring professional installation from an Authorized Geotab Installer are:
WARNING! Do not attempt to install, reconfigure, or remove any product from a vehicle while the vehicle is in motion or otherwise in operation. All installation, configuration, or removal must be done only in stationary vehicles which are securely parked. Attempting to service devices while the vehicle is in motion could result in malfunctions or collisions, leading to death or serious personal injury.
Locate the vehicle’s engine diagnostic port, typically found in the driver’s area at or below knee level.
✱ NOTE: For heavy-duty trucks, always use a vehicle-specific harness when offered by Geotab or the vehicle manufacturer (see Harness Identification and Application and Harness Assessment Cheat Sheet). Where a heavy-duty truck-specific harness is not offered by Geotab or the vehicle manufacturer, use the adapter harness (HRN-CG13S1) for any 16-pin (OBDII) installation method to avoid possible GO device damage.
Align the receiver end of the device with the engine diagnostic port and push in place. Please ensure the device is well-connected to the diagnostic port. Once connected, the device emits 6 quick beeps.
Once the device is connected and receives power, the LEDs on the front of the device start blinking then turn solid once completing the actions below.
Red LED — Device configuration
Green LED — Cellular network connectivity
Blue LED — GPS network connectivity
The device emits two quick beeps every 60 seconds during set-up. Initial startup may take several minutes to complete.
Once all three LEDs turn solid and you hear 10 quick beeps, secure the device using the provided cable tie.
✱ NOTE: The device is considered installed when the Green and Blue LEDs turn solid.
When performing under-dash installations with an extension harness, make sure the antenna side points upwards — towards the sky for faster GPS latch times. The GPS antenna in the GO9 is located on the bottom of the device.
Navigate to installmygps.com and open MyInstall (public) to verify that the device is communicating. Under the Installer Information, enter your name and your company name, and then press Next. Under Device serial number, enter your GO device serial number, found at the bottom of the device, and then press Validate.
The Device Status displays a PASS or FAIL label to inform you of the status of the device. The PASS status indicates that the device has successfully communicated with the network in the last 24 hours. The FAIL status indicates that the device has not communicated with the network in the last 24 hours.
✱ NOTE: If the device is not communicating, please ensure the GO Device is installed correctly and try again.
Press Next to go to the Vehicle information section. Enter vehicle related information: vehicle name, license plate, VIN, make, model, year, odometer, engine hours, work order reference, and installation comments. You can manually enter the Make, Model, and Year fields or tap the search icon beside VIN to auto-populate them. If you enter the Odometer value, you must select a unit of measurement (km or miles). You can use the Work order reference field to enter the work order number. You can enter Installation comments if desired. Tap Finish installation to complete the installation.
✱ NOTE: For some vehicle makes and models, the auto-populate option might not be possible.
Please refer to the MyInstall User Guide for more information.
WARNING! All in-vehicle devices and related cabling must be securely fastened and kept clear of all vehicle controls, including gas, brake and clutch pedals. This requires the use of a cable tie when securing the device or any extension harness to the OBD connector, securing both sides of the harness. If you do not use a cable tie, vibration in the vehicle can lead to a loose connection which could indirectly cause the vehicle’s engine computer to fail, loss of vehicle control and cause serious injury. Inspect devices and cabling regularly to ensure all devices and cables remain securely attached.
WARNING! If at any point after an in-vehicle device is installed a warning lights up on the vehicle dash or the vehicle stalls or has a marked drop in performance, shut off the engine, remove the device, and contact your reseller. Continuing to operate a vehicle with these symptoms can cause loss of vehicle control, and serious injury.
For the latest version of the Limitations of Use, please visit: goo.gl/k6Fp0w.
WARNING! Your in-vehicle devices must be kept clear of debris, water and other environmental contaminants. Failure to do so may result in units malfunctioning or short-circuiting, that can lead to a fire hazard and cause loss or serious injury.
WARNING! Do not attempt to remove the devices from the vehicle in which they are originally installed for installation in another vehicle. Not all vehicles share compatibility, and doing so may result in unexpected interactions with your vehicle, including sudden loss of power or shutdown of the vehicle’s engine while in operation or cause your vehicle to operate poorly or erratically and cause serious injury and/or vehicle damage.
